Sun Qi has a headache, you must know that to make a mirror, if you use the power of the machine, you only need the raw quartz sand and natural soda, and then consume a white essence, you can take out the mirror immediately, but Sun Qi doesn't want to do this. Pen % fun % Pavilion www.biquge.info

Machine-making, is a technical work, Sun Qi does not want to transform this ability into clothes to reach out for the good and bad work, he must complete a quantitative change to a qualitative change, must be able to do it himself, complete those new products, otherwise how to convince the public in the future, as soon as the hand stretches out, a shrink, take out a new thing, this is unlikely, and others are more of a contempt.

Fortunately, he can freely access the drawings, and the drawings of this silver-plated mirror, Sun Qi can unlock it, Sun Qi decided, this time to make it himself, do it himself, and have enough food and clothing.

The assassin decided to provide Sun Qi with all the materials he needed, but the consequences were also very serious.

"If you can't make it, don't wait for that closed-door cannon, and take the exam in the next life!"

You must know that during the imperial examination, once the entrance time of the examination has passed, the government will fire two cannons to show that the door is closed, and the candidates behind are not allowed to enter, unless they have the permission of the examiner.

"Don't worry, I never missed anything."

Sun Qi said confidently, but there were some worries in his heart, this time he made it himself, and he used to make the finished product directly, but this time he had to follow the order of the drawings, step by step.

To make a mirror, it is necessary to make glass first, and then the silver mirror reaction occurs, and the manufacture of silver mirror can be said to be difficult but not difficult.

Of course, the technique is fixed, you know, the way to make glass is not difficult, as long as the natural soda is mixed with quartz ore and heated, the sparkling crystals formed are glass.

After leaving the boudoir, he and the Assassin went to a large courtyard, where Sun Qi set up a cauldron with water, and put a few piles of firewood underneath to light it to boil.

"What about the materials? Xiaosheng wants natural soda and some quartz sand, the girl should have it! ”

The assassin said impatiently: "It's so troublesome to make something, thanks to my fox Xiaoqi who traveled south and north, and collected countless rare treasures, you go to that treasury to see if there is anything you want." ”

She wasn't good at reading in the first place, let alone the chemistry that was so different from her.

Sun Qi walked into the treasure room, and silently said in his heart, 'Glass luster, block-like ....."

In a pile of so-called rare treasures, Sun Qi finally found a bunch of things with the above conditions, found a bunch of natural soda, and some quartz sand, fortunately, Sun Qi had a good study of chemistry in his previous life, otherwise he really didn't know where to start, and the drawings pointed out the way to identify quartz sand.

"Well, that's it, that fox Xiaoqi really traveled south and north, and natural soda can only be found in arid lands, but I didn't expect it to be collected by her."

Sun Qi found a piece of precious quartz sand under some gold and silver jewelry, you must know that Hu Xiaoqi has been engaged in killer work all year round, involving people from various industries, from alchemy to mining, everything is available, that is, every time she kills someone, she will take a representative thing from the victim as a souvenir.

"Next, put these two pieces of things in and cook, it should be, the drawing says so, if this drawing deceives me, my little life will be left here."

Sun Qi threw a piece of quartz sand and the pile of natural soda into the boiling pot, and then prayed silently in his heart, deliberately not looking at the fox eyes that overlapped with fox Xiaoqi's murderous aura, he just silently looked forward to it, he must succeed, even if he got a glass block, as long as there was a glass block, he could be silver-plated, make a mirror, and satisfy this murderous female devil.

Sun Qi knew from the mouth of this female demon that she had assassinated more than a thousand people, and Sun Qi was secretly frightened.

"Are these two pieces of your stuff useful? Otherwise, just wait for the knife! ”

Time passed minute by minute, the medicine in the pot had already dissolved in water, and the thing did not react for a long time, just when Sun Qi was about to despair, the thing in the pot finally reacted.

Even Hu Xiaoqi looked at the miracle that happened in the pot in amazement, she had only seen some chemical reactions in some alchemists' homes before.

The boiling water began to be full of crystalline particles, and then in a quarter of an hour, it coalesced into a single piece of crystallization with the natural soda that also melted.

Sun Qi breathed a sigh of relief in his heart, according to the drawings, the first step of glass manufacturing only uses the first convenient manufacturing method, of course, it cannot be mass-produced, and the second manufacturing method will be used when it is promoted in the future.

"This is what glass is?"

Fox Xiaoqi's eyes widened in surprise, and he glanced at the plate in the pot, which was crystal clear, reflecting all kinds of luster, and it was extremely beautiful.

"This thing isn't very reflective, what's next?"

Hu Xiaoqi is not a fool, he knows that this is just one of the simple steps, and the mirror is not so simple to get out.

"I'll have to go to the girl's treasure room again and look for something useful."

After getting the permission of Hu Xiaoqi, Sun Qi entered the treasure room.

The purpose of going in for the second time was to find three kinds of medicines, and of course, the chemicals of the new era were replaced with common names on the drawings.

For example, the ammonia water that has a silver mirror reaction, known as Ammonian water in ancient times, this kind of thing, Sun Qi found it in a jar, and Sun Qi secretly praised the rich collection of this fox Xiaoqi.

Of course, he also found another pot of medicine, sodium hydroxide, commonly known as caustic soda, Sun Qi said secretly, if it weren't for the rich collection here, I'm afraid I would really have to hang it here.

"How do you make another type of silver nitrate?"

Sun Qi wondered, there was no such thing as silver nitrate in ancient times, silver nitrate needed nitric acid, and there was no nitric acid in ancient times, but Sun Qi saw a method for making nitric acid on the drawings, and the mixture of green alum and saltpeter could be distilled to obtain a nitric acid solution.

Sun Qi was overjoyed, the green alum had just seen it, but what Fox Xiaoqi collected was a kind of crude green alum, which was a piece of green sand-like crystal, which was also commonly known as gallstone, and the ancients often used it to decorate the courtyard, and there were many of this fox Xiaoqi here.

Saltpeter is a natural mineral, what Sun Qi didn't expect was that Hu Xiaoqi also had it here, in fact, there was saltpeter under the corner of the eaves, and it was another trouble to solve.

"The next thing is to find a ceramic."

"Hey, are you out? Girl, I can't wait! ”

The process of heating a solid substance to a high temperature to decompose it under the condition of isolating the air is called dry distillation, and finding a closed ceramic jar is to isolate the air.

Hu Xiaoqi saw Sun Qi walking back and forth in the garbage room, and after a while, he set up a ceramic pot in the courtyard.

Curious, she didn't interrupt.

"Put this alum and saltpeter into it, add some water, and after dry distillation, the liquid obtained is a nitric acid solution, and after nitric acid is obtained, silver nitrate can be made."

After heating for a while, there was a fluttering sound in the ceramic pot, and Sun Qi said secretly, nitric acid came out.
